【 摘 要 】

The codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is a significant pest of pomefruit and walnut orchards worldwide and it is a particular problem in Bulgaria. Codling mothresistance to many insecticides has been recently detected in Bulgaria. Codling moth (CM) matingdisruption with Ginko® dispensers was evaluated in four successive years from 2019 to 2022 aspart of an anti-resistance strategy. In an isolated 3 ha apple orchard in the Plovdiv district of SouthCentral Bulgaria, close to the town of Perushtitsa, field tests were conducted for the control of thecodling moth (CM), C. pomonella, via mating disruption (MD) using pheromone Ginko®dispensers. The pheromone dispensers were hung in the upper third of tree canopies with a densityof 500 dispensers/ha before CM flight started. Dynamics of CM flights was monitored bypheromone traps installed in the trial plot and in a conventionally treated reference orchard. Twotypes of baits were used in the traps: PHEROCON® CM L2–codlemone lures and PHEROCON®CM DA COMBO-P + AA lures (Trécé Inc., USA) in the orchards for mating disruption. ThePHEROCON® CM L2 lures were changed at 4-week intervals and PHEROCON® CM DACOMBO-P + AA lures at 8-week intervals. PHEROCON® VI Delta sticky traps baited withPHEROCON CM DA COMBO- P + AA lures and standard CM L2 caps were installed, forcomparison, in a reference orchard located in the Plovdiv region. Fruit infestation was periodicallyassessed till the harvest time. In both years fruit damage remained lower till late July and increasedslightly only in August. At harvest, fruit damage remained below 1%. It was obvious that matingdisruption could be useful strategy for the control of codling moth in Bulgarian apple orchards,specifically when the plot is isolated from external sources of infestation and the populationdensity of the pest is low.
